Don't do anything too implusive. "Heading south" might seem a viable option, but I'd hope you'll have your ducks in a row before jumping in. FWIW, I'm 56 & my father's 77; we still get into it on occasion, & I have a hard time spending more than a few days with him & my mother. I know I should be grateful I still have them, but parents never lose their ability to push one of our buttons sometimes. I wish you luck, whatever you decide.
